29 Amphitrite (am'-fi-trye'-tee) is one of the largest Main belt asteroids. It has a relatively bright surface and a composition of silicates rock and iron-nickel metals.
Amphitrite was discovered by Albert Marth on March 1, 1854. It was his only asteroid discovery. It is named after Amphitrite, a sea goddess in Greek mythology.
A satellite has been suggested based on the lightcurve data. [1] (http://www.johnstonsarchive.net/astro/asteroidmoonsq.html)
